To ALL WHQM Ir MAY(.:tnrosn'1-t5 Be known that I, VJAMES M. SEYMOUR; .of the cityof Neivark, inthe county of Essen, and State 'of New. Jersey, have made'certain Improvements-in Spacing and'Boring-Machines and I do hereby declare the following to be a, full and exact descriptionotf the same referencebeing herein had Vtothe drawings that accompany A this specification Vas part. of "thesama The nature of myimprovement consists in c'provisi'oafor boring holes in-blind-stiles, orrin anystn that requires holes at,regular or irregular distances, which, when properly sci ,zrequires no `furtherattention 'as toy distancing theholes from the operator. f In the drawings Figure 1 is the complete lmachine, with some of its front removed to sliow the parts behind.

Fignrez is a partoff the 'sliding notchstick'and its helder. v

Figure Bis a bell-crank and its connections ;v and i Figure Ithe sliding gangeor pawl-lifter.- The same letters referV to the same paitsin'each figure. A Upon the front of the machine is-the'usual adjustable table z, upon whichthcpieoe to be bored. is placed. The1 end of the common adjustable fence for regulatingthe'distancesgof the holes from the edge of thefp-iece to be bored is shown ahy, and ntopviewo the same atg, iigl. Aslide, "1x, is fitted so'as tomove-fredyupoh the fence y, in the inside o'fgvvhichslid'e ,there is a. groote to receive a. notched 4sti-cli, 1o. slotismadeltbrough the f ejncedy, in the part shown b ykthe dotted'lline in 4. Behind the fence y! attached to the main filame A-of the machine,A is a. slotted bar, W, in v vhich aslide, o, moves easily, carryingapaxvhu, and spring t. bell-crank,

s, takes hold of the pin ron the backy ot"thc slide-n.1 lThe"bell-clank.is connected with the rod by a. crotch or slot, through which the rod passes. Above and belovv the arms ofthe'lbell-crank, u pon the ro'd o, are collars n n; adjustable by set-screws. "The lower end` of the rod o is attached to atieadle, m, 'and the upper end to the slidinghead in` which arethe'boring-bit Aland the stop k. A spiraVepring, .Lcar'ries up the rod and head after heing'forced downbythc treiadle.` A stopte', is putbetiveen the top ot' the spring J and the bark in the `1 main frame A. This-stop being acollar movable uponthe rod' o, can, by'its set-screw, be placedso as to allow .more or less rise ofthe sliding headJQB and 'of the bell-*crank s. It v vill beseen that'by depressing the treadle;

the slide @with pawl u and spring t, is by the bell-'crank draivnbachfso that thepawl catches a. notch in the stick p, which upon release of the lever movesv forward justasfar: as the stopt' will. admit, the space between the collarsjn n beingso adjustedthat the boring-bit Zshll have time to clear the piece bored; before the notched.V .stick p andthe slide a: commence moving forward. The stile or piece'to be bored is held bythe lhand against the face of the slider, with its end against the pin g, and its bottom 'close down upon the table e. The patvl u passes through thei'ence gto-the notched'st-ick p. To Vthe bacli'of#V the fence y, a sliding gauge,f, is attached, which is operated'by-hand. 'When passed forward to its extreme it lifts the paul u' out ofthe'notched stick, and allows the stick and slide to return back freelyupon the fence. and can bemade -available forthe purpose of lifting thepatvl out of longer or shorter notchcs,"as maybe required.

Ot' the right tofthisas used in the machinei'oi wiring bli'ndJaths, I :im administrator and owner, in the right of vthe patentee, (deceased,) T.'R Crossby; of Newark. f

I am aware of the use of the stationary notched stick for boring purposes; and also of the movable notched stick for iviring window-blinds. i Y

1. The combination of the bell-cranksV for moving` the slide irgend the 'adjustable stops n n and z', so

arranged that the action of said ranlt shall uiovc the slide as soon' as the bit is raised out' of the Woodp'when i operated substantially i-n the manner-set forth.

2. The arrangement of the fence y, slide x," and removable notched stick 1o, and reciprocating pawl u, con strncted and operated'substantially as and for'the purpose sot forth. Y
